Hello.
Thank you for visiting the TECH & DIY channel.

The 24th content is the maximum rotational speed of the NEMA17 stepper motor via the A4988 driver and function generator.
Measurement test.
When a square wave is input to the STEP pin of the A4988, the stepper motor rotates.
Let's check the maximum operating frequency for each microstep.
There is no load on the stepper motor.

The contents of the contents are as follows, and if you click the timestamp, the contents are played.

00:16 Test circuit wiring diagram
00:26 Full Step rotation speed test
02:19 1/2 Step rotation speed test
04:12 1/4 Step rotation speed test

Interesting that the rotation speed where it would reliably restart was roughly the same for all the step modes.

How much ohm did you use to connect DIR and STEP - and why not connect them without?

How many degrees Celsius does it heat up when it gets to its max speed?
